Lords and Ladies: The Spectacular Harlequin Duck

A drake Harlequin Duck, Histrionicus histrionicus, in repose. This species, in my estimation, is one of the most elaborate and eye-catching of the world's fowl. That's saying something as there are a lot of beautiful ducks afloat on the globe. It's as if Pablo Picasso was commissioned to create a cubist collage of a bird.

Last weekend saw me visiting the City of Brotherly Love, Philadelphia, to speak at a symposium at the sensational Longwood Gardens. Once that gig was complete, it was into the car for a short two hour drive to the Atlantic Coast and one of my favorite seaboard locales, Barnegat Light, New Jersey. There I met up with a friend from The Blogosphere, Amy of Chatter from the Wren's Nest. That's Amy glassing the waters of Barnegat Bay and being bedazzled by all of the interesting waterbirds.

Wintertime birding at Barnegat is always interesting, and especially so when the tide is rolling out. Amy and I hit it perfectly, as mid-morning saw the bay's waters rushing seaward with the force of a whitewater rapids river. All of that hydrological turbulence stirs up the food, and birds descend on the mouth of the bay in droves.

But the Harlequin Ducks can nearly always be easily found, as their diet consists of much more sedentary prey. Here, a small feeding flock works the waters just off Barnegat's long stone jetty.

A drake snorkels for food. He is skimming along with his face under the surface, scanning for tasty morsels. Once a good meal is located, he'll dive down and wrench his aquatic prey from the substrate.

A pair of rather muted females flank a gaudy drake. This disparity in flashiness between the sexes leads to one the colloquialisms for this species, "Lords and Ladies".

These ducks were nearly at my feet, perched on rocks at the base of the jetty. And they are literally standing on their food. Low tide has exposed thickets of blue mussels, Mytilus edulis, a common North Atlantic mollusk. Harlequins are very much birds of the brutal interface of sea and rock, expertly diving in the turbulent waters to exploit mussels in a nearshore zone that other species of sea ducks shun. Such rough work has its costs. Supposedly a fair number of Harlequin Duck museum specimens show evidence of bone fractures, probably due to battering against rocks in the surfy chop in which they ply their trade.

If you've not birded Barnegat, toss the trip into your bucket list. It's worth it for the Harlequins alone. But there is much, much more. I returned from this foray with an armful of good photos of many interesting species of birds - many of them great rarities in my landlocked neck of the woods. I'll probably be sharing a few more of Barnegat Light's birds before long.

What spectacular ducks! Thanks so much for your great observations!

Good grief. I thought you were making up their scientific name to see if we were paying attention... ::face/palm::

Thanks for your comments! Yes, the Harlequins are outrageous animals, and they alone merit the trip to Barnegat.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.


So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
